Emails for Wall Street Breakfast are all of a sudden unreadable due to small font

Starting sometime last week (July 16-20 2018) the emails I get on my Android are now so small they cannot be read. What did you change? To me it looks like the AD's are displacing the text and making it too small to read. I have no choice but to delete them. It happens on the Wall Street Breakfast, SA Dividends & Income and SA Stock Ideas Daily. Please make it so I can read those emails again.
